Good.iWare’s popular document and file management iOS app, GoodReader, is one of the best applications to help solve the lack of a dedicated file management system on your iPhone, iPod touch and iPad devices.

GoodReader can synchronize your documents and files with a number of sources, be it your computer, another iOS device or a host of frequently used cloud-storage solutions.

It has a robust PDF management and editing capabilities that have been vastly enhanced in the latest version 4.0 update. Having decided to release GoodReader 4 as a brand new paid app, Good.iWare is now offering a time-limited 60 percent discount with an introductory price of $2.99…

Here’s the new (right) vs. old (left) app icon.

Not much of a difference, eh?

More important than the app icon, GoodReader 4 comes with a host of PDF editing capabilities, on top of all the features from the previous version.

For starters, the new PDF Page Management option allows you to easily add, rearrange, delete, rotate, extract and email individual pages of a PDF document, as well as split and merge files.

Your PDF Page Slider now shows page previews, there’s a new icon view in the file browser with larger document previews and the tool area on the main screen is now collapsible.

Other highlights include:

• Insert blank pages for notes and drawings, solving the problem of not having enough space to annotate or draw images on a document

• Rearrange pages in a document

• Rotate individual pages – or even all of them

• Delete any pages from a document

• Extract individual pages as separate files, and split PDF files into halves – enabling a sub-set of pages to be shared as its own file

• Email individual pages rather than the entire document

• Append pages from other PDF files

I’ve also found a New PDF option very useful as it lets me create an empty PDF document from scratch.

If you’re transitioning from the previous version, the Migration Assistant will take care of transferring your files and setting from the old GoodReader to GoodReader 4.
